This kind of forecast doesn't depend too much on the

models (i.e. via paleo - climate data), moderated by the thermal inertia of the oceans and assuming the (very likely) continuation of CO2
emissions at present or accelerated
rates.
Rate of percentage annual growth for carbon dioxide has certainly increased since the beginning of the 21st century, but this should result in a significant change in the rate of warming any more quickly than the differences between emission scenarios would, and there (according to the models) the differences aren't significant for the first thirty - some years but progressively become more pronounced from then on — given the cummulative effects of accumulated carbon diox

First, the original
emission rates of SO2 and H2SO4 (3 % of total anthropogenic SO2 emitted) in the

It may be worth considering that if climate
models are underplaying the actual amount of Arctic sea ice loss, and if Arctic sea ice loss is a positive feedback on global temperature, then, the observed
rate of Arctic sea ice loss ought to be applying a warming pressure over and above that from greenhouse gas
emissions.

Yet, despite the fact that the
models systematically overstate the costs of cutting

rates.

However, there remains uncertainty in the
rate of sea ice loss, with the
models that most accurately project historical sea ice trends currently suggesting nearly ice - free conditions sometime between 2021 and 2043 (median 2035).12 Uncertainty across all
models stems from a combination of large differences in projections among different climate
models, natural climate variability, and uncertainty about future
rates of fossil fuel
emissions.
«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The
rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the
rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate
models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected
rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2
emissions (reducing
emissions in 2050 by 80 % compared to today's
rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2
emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
